Abstract

Discrepancy between the measurements of Hubble constant H0 from the cosmic microwave background and the local distance ladder is the most serious challenge to the standard ΛCDM model. Recent research has pointed out that it might be related with the violation of cosmological principle. Here, we investigate the impact of dipole–monopole correction on the constraints of H0 utilizing the dipole-fitting method based on the ΛCDM model and cosmography method. Our results show that the dipole–monopole correction can reduce the constraints of H0 from a larger value consistent with SH0ES results to a smaller value consistent with Planck results. This finding can effectively alleviate the Hubble tension. Through making redshift tomography and model-independent analyses, we confirm that our findings are independent of the redshift and cosmological model. In addition, the theoretical prediction of H(z)/(1 + z) reconstructed by the constraints of the ΛCDM model with the dipole correction is in agreement with baryon acoustic oscillation (BAO) measurements, including five Dark Energy Spectroscopic Instrument BAOs within the 1σ range except a data point at z = 0.51. Our research suggests that the Hubble tension originates from new physics beyond the standard ΛCDM model, which might lead to a violation of the cosmological principle.
哈勃张力的新物理学提示:违反宇宙学原理
宇宙微波背景测量的哈勃常数H0与本地距离阶梯之间的差异是对标准ΛCDM模型最严峻的挑战。最近的研究指出,这可能与违反宇宙学原理有关。在此,我们利用基于ΛCDM模型的偶极子拟合方法和宇宙学方法研究了偶极子-单极子修正对H0约束的影响。结果表明,偶极-单极校正可以将H0的约束条件从与SH0ES结果一致的较大值减小到与普朗克结果一致的较小值。这一发现可以有效缓解哈勃张力。通过红移层析和与模型无关的分析,我们证实了我们的发现与红移和宇宙学模型无关。此外,通过偶极子修正的ΛCDM模型约束重建的H(z)/(1+z)理论预测值与重子声振荡(BAO)测量结果一致,其中包括5个1σ范围内的暗能量光谱仪BAO,只有z=0.51处的一个数据点除外。我们的研究表明,哈勃张力源于标准ΛCDM模型之外的新物理学,这可能会导致违反宇宙学原理。
